When the Moon and the Sun are on opposite sides of the Earth, and the ecliptic longitude of the Moon and the Sun differ by 180 degrees, the side of the Moon facing the Earth is fully illuminated from the Earth, and the Moon is the roundest at this time, which is called the "Full Moon", also known as "Wang".

Since the moment of 'looking' in the first month of the Year of the Dragon occurs at 20:30 on February 24, the Lantern Festival of the Year of the Dragon is 'the fifteenth moon and fifteenth round'.

On February 15, 2022, the Lantern Festival, "the moon of the fifteenth is seventeen round". This is the Lantern Festival Moon photographed by Zheng Zhi, a starry sky photography enthusiast in Beijing, on February 15 in Beihai Park, Beijing. (Photo courtesy of me).
Coincidentally, this round of Lantern Festival Moon is also the "smallest full moon" this year. Xiu Lipeng introduced that the moon itself does not emit light, and the moonlight we see comes from the sunlight reflected by the moon. The Moon revolves around the Earth in an elliptical orbit, and the distance between the Moon and the Earth is not constant. Because the distance is different, the moon in our eyes is also divided into sizes. If the Moon is near apogee during the Full Moon, the Full Moon will appear smaller, and conversely, if the Moon is near perigee, the Full Moon will appear larger.

There are usually 12 or 13 full moons in a calendar year. The Full Moon on February 24 is the closest to apogee of all the Full Moon days of the year, making it the "Smallest Full Moon" of the year. This year's "biggest Full Moon" occurs on October 17 (the 15th day of the ninth month of the lunar calendar). The public who are interested can take pictures of this "small and big" and compare them to see how much worse.

How to enjoy this Lantern Festival in the Year of the Dragon? "The best way to see the moon is within two hours after sunset and around midnight. This is because the moon appears large and round shortly after sunset, which is not only suitable for viewing with the naked eye, but also for taking photos with the ground landscape; Around midnight, the full moon 'walks' to the vicinity of the zenith, and it will form a beautiful scenery of 'bright moon illuminating in the headspace'. At this time, the horizon of the Moon reaches its highest level all night, and the atmosphere through which the moonlight passes is thin, so the Moon looks crystal clear. Xiu Lipeng suggested.
